When scientists send up spacecrafts do they think of bringing them back down?

ans:- Sometimes

For example , when an astronaut goes into space it is most definitely going to come back with the astronaut inside it. The ISS ( International Space Station ) was sent up into space to collect information about outer space ; therefore it will keep on orbiting the earth until the mission ends.

But what happens when the mission has ended ?

ans:-Blow it up or make it 'self-destruct'.

Some space junk results from collisions or anti-satellite tests in orbit. When two satellites collide, they can smash apart into thousands of new pieces, creating lots of new debris. This is rare, but several countries including the USA, China and India have used missiles to practice blowing up their own satellites.

Back on earth, we humans pollute a lot .From the air to the oceans , pollution exists.We have realised that this is a problem; therefore we have started to re-cycle and pick up our rubbish.And because of the advanced technology we have, there are also more economical cars around us. All we need to do now is start to figure out how we can carry on sending up things as long as they come back in one piece (without leaving any debris.)

What do you think?
